Abstract
Disclosed is a transverse pipe-array type heat exchanger used in oil-gas field natural gas, oil field associated gas processing course with medicament (such as antifreeze, corrosion Inhibitor) added in natural gas of pipe side inlet. on the basis of common pipe-array type heat exchanger, the arrangement method of the heat exchange pipes of the pipe-array type heat exchanger is changed, a plurality of heat exchange pipes are arranged on the same level plane to form a transverse line, a corresponding horizontal pipe side barrier is arranged in the pipe box to form a pipe side. the horizontal-array heat exchange pipes are arranged to form the same quantities of pipe sides. the medicament added in the natural gas can enter evenly the heat exchange pipes of the pipe-array type heat exchanger. If the medicament is an antifreeze, the antifreeze can effectively prevent water in natural gas from forming the water composition and/or ice, and prevent the pipe side of the heat exchanger from being jammed, and prevent the pressure difference at inlet and outlet of pipe side of the heat exchanger from being increased, and prevent the heat conduction effect of the heat exchanger from becoming poor. If the medicament is a corrosion inhibitor, the corrosion inhibitor can effectively prevent the corrosion of the heat exchange pipe.
Description
Affiliated technical field
The utility model relates to a kind of oil, gas field natural gas, associated gas process of being used for, be added with the horizontal tubular heat exchanger of medicament (antifreezing agent, corrosion inhibiter) in the tube side inlet natural gas, in the tubular heat exchanger heat exchanger tube that especially medicament that is added with in the natural gas can be distributed equably into.
Background technology
General tubular heat exchanger is made up of housing, heat exchanger tube, tube sheet, bobbin carriage and end socket.To be fixed on the tube sheet at the some horizontally-arranged heat exchanger tubes in certain zone, level, vertical pass partition are set in bobbin carriage, form a tube side.In a tube side, some heat exchanger tube is in top, and some heat exchanger tube is in the bottom.After the natural gas that is added with medicament entered bobbin carriage, flow velocity reduced, and the medicament separation of particles that diameter is big is sunk, and the medicament distribution occurs inhomogeneous in the natural gas.The medicament that enters in this tube side top heat exchanger tube is just few; And the medicament that enters in this tube side bottom heat exchanger tube is just many.If medicament is an antifreezing agent, just form hyrate and/or ice in this tube side top heat exchanger tube.Hyrate and/or ice stop up the fluid passage, and heat exchanger tube side inlet outlet pressure differential increases; Hyrate and/or ice are carried out and are covered heat exchanger tube heat-transfer area, heat exchanger tube heat-transfer effect variation.Full-bodied antifreezing agent more in this tube side bottom heat exchanger tube reduces the heat transfer coefficient of bottom heat exchanger tube, the heat-transfer effect variation attached on the heat exchanger tube inwall.If medicament is a corrosion inhibiter, just form corrosion in this tube side top heat exchanger tube.Make heat exchanger tube heat-transfer effect variation too much owing to the low corrosion inhibiter of thermal conductivity factor in this tube side bottom heat exchanger tube.
At present, the influence of medicament heat exchanging device heat exchange research is less.U.S. John M.Campbell work " natural gas preliminary treatment and processing " provides the correlation of fluid density and minimum velocity in pipes, proposes to make medicament well distributed between each heat exchanger tube by improving velocity in pipes.But velocity in pipes too high pressure drop is just very big, and flow velocity is still low in the bobbin carriage, does not solve medicament and separates in bobbin carriage and cause problem of uneven distribution between each heat exchanger tube.
Summary of the invention
In order to overcome medicament problem pockety in the horizontal tubular heat exchanger tube side natural gas, the utility model improves on the basis of general tubular heat exchanger, and medicament can distribute in each root heat exchanger tube uniformly in the tubular heat exchanger tube side natural gas after the improvement.
The technical scheme that its technical problem that solves the utility model adopts is: the arrangement mode that changes the tubular heat exchanger heat exchanger tube, some heat exchanger tubes are arranged on the same horizontal plane, form a horizontally-arranged, be fixed on the tube sheet, corresponding horizontal pass partition is set in the bobbin carriage, forms a tube side.Heat exchanger tube in one tube side does not have the difference of top heat exchanger tube and bottom heat exchanger tube, how many horizontally-arranged heat exchanger tubes is set just forms how many tube sides.The heat exchanger tube quantity that each horizontally-arranged is arranged does not wait, by its place horizontally-arranged comb determining positions.Arrange by general tubular heat exchanger triangular pitch between the heat exchanger tube in the one horizontally-arranged heat exchanger tube.Horizontal pass partition only is set in the bobbin carriage, the horizontally-arranged heat exchanger tube on same horizontal plane is divided into a tube side.The cydariform vertical clapboard is set in the left pipe box, stretches into the degree of depth in the bobbin carriage to reduce horizontal pass partition, convenient welding.The bobbin carriage skull is provided with atmospheric valve.After the natural gas that is added with medicament enters bobbin carriage, flow velocity reduces, the medicament particulate that diameter is little enters in the heat exchanger tube with natural gas together, on the separated medicament liquid level that sinks to down on the horizontal pass partition of the medicament particulate that diameter is big (the medicament liquid level is in the lower limb position of the first horizontally-arranged heat exchanger tube mouth of pipe when normally moving), then, the medicament on the liquid level is carried by natural gas and evenly enters in each heat exchanger tube of first horizontally-arranged that is provided with on same horizontal plane.Other end bobbin carriage (heat exchanger tube is this bobbin carriage of U-shaped Guan Shiwu) at heat exchanger tube, flow velocity reduces, on the separated again medicament liquid level that sinks to down on the horizontal pass partition of the medicament particulate that diameter is big (the medicament liquid level is in the lower limb position of the second horizontally-arranged heat exchanger tube mouth of pipe when normally moving), medicament on the liquid level is carried by natural gas and enters in each heat exchanger tube of second horizontally-arranged (when heat exchanger tube is the U-shaped pipe, two straight lengths of plurality of U-shaped pipe are arranged on two adjacent horizontal planes, form upper and lower two horizontally-arrangeds, i.e. the first horizontally-arranged heat exchanger tube and the second horizontally-arranged heat exchanger tube.Form two tube sides).So from high to low, the natural gas that is added with medicament flows out from descend most the horizontally-arranged heat exchanger tube, discharges from the tube side outlet, realizes that a horizontally-arranged heat exchanger tube is the heat transfer process of a tube side.In heat exchanger tube, the natural gas flow state that is added with medicament is a turbulent flow, and medicament can be evenly distributed on the heat exchanger tube inner surface.
The beneficial effects of the utility model are, in the tubular heat exchanger heat exchanger tube that the medicament that adds in the natural gas evenly can be distributed.Medicament is if antifreezing agent can prevent effectively that moisture content forms hyrate and/or ice in the natural gas.Prevent that the heat exchanger tube side from stopping up, prevent that heat exchanger tube side inlet outlet pressure differential from increasing, and prevents heat exchanger tube heat-transfer effect variation.Medicament is if corrosion inhibiter can effectively prevent the heat exchanger tube corrosion.
